ENVELOPE Filed m 3, 1929 Patented Sept. 15, 1931 UNITED STATES PAUL MILLER, OF CHICAGO, ILLINOIS ENVELOPE Application filed May 3,

My invention relates to envelopes, and more particularly to an envelope formed from a single blank by folding.

An object of the invention is the provision of an envelope so shaped and constructed that either end of the envelope may be torn or otherwise severed without damaging or mutilating the contents of the envelope.

Another object of the invention is the pro- 19 vision of an envelope having its ends so shaped or formed as to provide guides or indicator points by means of which the address may be written in aligned parallel relation to the longitudinal edges of the envelope.

Another object is to generally improve envelopes of the kind described.

A further object of the invention is to provide an envelope of the kind described which is simple, eflicient and satisfactory for its intended purpose.

Many other objects and advantages of the construction herein shown and described will be obvious to those skilled in the art from the disclosure herein given.

To this end, my invention consists in the novel construction, arrangement and combination of parts herein shown and described, and more particularly pointed out in the claims.

In the drawings, wherein like reference characters indicate like or corresponding parts,

Fig. 1 is a plan view of a complete blank or sheet from which the envelopes are produced before being folded; and

Figs. 2 and 3 are the front and rear view respectively of the completed envelope formed by folding along the dotted lines of Fig. 1.

Referring now more particularly to the drawings, in producing the envelope a sheet or blank 1 is so cut that the same may be folded and formed into an envelope having the general shape or contour shown in Figs. 2 and 3. The blank 1 is provided with oppositely positioned end flaps 6 which, in forming the envelope, are folded along the dotted lines 7 of Fig. 1. End flaps 3, which are preferably symmetrical about a trans- 0 verse axial line, are folded along lines 5 Serial No. 360,676.

shown dotted in Fig. 1. A lower flap 2 is folded along the dotted line 9 of Fig. l to the position shown in Fig. 3. The envelope is completed, ready for use, by folding the top flap 4 along the dotted line 8 of Fig. 1 but leaving the same unsealed.

Theoverlapping portions of the flaps 2, 8,

1, and 6 may be provided with adhesive material, such material not being shown, inasmuch as the invention is believed to reside 69 in the blank forming the completed envelope and the shape of the flaps forming a portion of the blank.

The dotted lines of fold 5 and 7, are preferably symmetrical relative to both the 1011- gitudinal and the transverse axial lines of the completed envelope. By inclining the lines 5 and 7 to the transverse axis of the envelope, pointed projecting ends terminating in ,apices 11 are formed, providing a safety 79 margin within which the contents of the envelope will project only slightly or not at all, if the contents are folded to a width substantially the same as the width of the en velope. The adjacent flaps 3 and 6 are separated by reentrant angles or spaces: 12 bounded by edges terminating at the intersecting points or apices 11. The pointed projecting ends permit the envelope to be opened, by tearing or otherwise severing 80 either marginal end, without damage or mutilating the contents. By making the lines 5 and 7 symmetrical about the transverse axial line of the envelope, the opposite intersecting points 11 of the lines 5 and 7 are respectively spaced at the same distance from the upper and the lower edges: of the envelope and if the lines 5 and 7 are made symmetrical about both the transverse and the longitudinal axial lines of the completed envelope, the points 11- will be equally spaced from the upper and the lower edges of the completed envelope.

Since the oppositely positioned points 11 are equally spaced from the upper edge of the envelope and are also equally spaced from the lower edge of the envelope, a line connecting the points 11 will be parallel to the sides of the completed envelope, and if the .lines 5 and 7 are made symmetrical about we both the longitudinal and the transverse axis of the completed envelope, a line connecting the points 11 will be midway between the side edges of the envelope, thereby serving as indicators or guides assisting in proper alignment of the written address to be placed on the envelope.

An inset 10 is formed on the inner portion of the upper edge of the flaps 3, the remaining portion of the upper edge of such flaps being curved to give an ornate eiiect to the rear face of the completed envelope. 7

The construction is such that the envelope may be made of any standard s ze or of any desired special sizes. The ratio of the Width of the completed envelope to its length may be varied as desired and the angle of inclination of the folds 5 and 7 may also be changed to vary the design. The shape and width of'the' spaces 12 between the flaps 8 and 6 may be varied as desired by changing the direction and the form of theinner bounding edges of'the flaps.

Thus it will be seen that I have provided an envelope having projecting ends forming safety margins: and that a sealed envelope so constructed may be torn open at either end without damaging or mutilatinp; the contents, andthat the ends are so constructed and formed as to assist in the alignment of the address with the side edges of the envelopei.

Having thus described, invention, it is obvious that various immaterial modifications may be made in the same without: departing from the spirit of my invention: hence, I do not wish to be understood asliiniting myself to the exact form, construction, arrangement and combination of parts herein shown and described or uses mentioned.

What I claim as new and desire to secure by Letters Patent is:

1. An envelope formed from a single piece oi material, comprising a main body portion having flaps at each side folded along parallel lines and having at each end a pairof flaps folded along lines forming obtuse angles with the sides of the envelope, the flaps at each end being separated by'a space converging to a point at the intersection ofsaid obtuse lines of fold.

2". An envelope formed from a single piece o-ii material. comprising a main body portion having flaps at each side folding along para-llel lines and having at each end a pair of flaps folding along lines forming obtuse angles with the sides of the envelope, the flaps at each end being separated by a space converging to a point at the intersection of said obtuse lines of folds, the intersecting obtuse lines of fold of the end flaps being symmetrical about both the transverse and the longitudinal axial lines of the completed envelope. v
